of sulfuric acid and toxic lead and its compounds. Electrolyte from spent batteries with concentration of sulfuric acid about 10 25% is contaminated with heavy metals, which difficult finding buyers for such product. Therefore, removing heavy metals (mostly Fe, Zn, Cd, Sb, Pb) and processing electrolyte into other product is mostly desirable.

Lithium Ion Battery Environmental Impacts ScienceDirect

Another key battery component is the electrolyte. While many possible electrolytes are being developed, we have selected lithium hexafluorophosphate (LiPF 6) in a solvent of EC and DMC. Little information exists on the production of LiPF 6, so its impact, although estimated on the basis of data presented by Espinosa et al. , is somewhat uncertain.

Hydration and Electrolytes Impact On Athletic Performance

Key Electrolytes in the Body. Body fluids (water) contain electrolytes. Electrolytes are salts of various types each of which play a critical role in physiology (function) and in athletic performance. The best known salt is so called table salt which is usually sodium chloride (NaCl).

Review and Evaluation of Alternative Chemical Disposal

In 1994 the National Research Council published Recommendations for the Disposal of Chemical Agents and Munitions, which assessed the status of various alternative destruction technologies in comparison to the Army's baseline incineration system. The volume's main finding was that no alternative technology was preferable to incineration but
